res_musiconhold: Added check for dot character in path of playlist entries to avoid warnings

A warning was triggered that there may be a problem regarding file
extension (which is correct and should not be set anyway). The warning
also appeared if there was dot within the path itself.

E.g.
[sales-queue-hold]
mode=playlist
entry=/var/www/domain.tld/moh/funky_music

The music played correctly but you get a warning message.

Now there will be a check if the position of a potential dot character
is after the last position of a slash character. This dot charachter
will be treated as a extension naming. Dots within the path then ignored.
